Panama has a tropical and humid climate with stable year-round temperatures of about 32ºC (90ºF) during the day and 21ºC (70ºF) during night time. However, temperatures vary according to geography; in highland areas like Boquete and El Valle de Anton, the annual temperature ranges from 12ºC (53ºF) to 15ºC (59ºF). Panama’s climate can generally be divided into two seasons.
The Dry Season: The dry-season usually lasts from December to May and is characterized by a stable, dry and sunny weather, with only some very occasional rain. These months are perfect for travelers seeking for sun and a usually well-predictable and stable climate. However, keep in mind that highland-regions like Chiriqui and El Valle de Anton, as well as some regions on the Caribbean side of Panama, like Bocas del Toro, Colon and the San Blas Archipelago, might have rainfall during this time.
The Green Season: During the months of June to November, the whole country is becoming lush and green. The season is characterized by sporadic rain showers which are vital for the tropical flora and fauna and as well as the water supplies of natural reserves throughout the country. Panama is perfectly fine to visit during this season. It may rain once a day for about two hours; however, before and afterwards it is usually sunny. During this time the country is lush and green, less crowded and prices are lower. There are also some regions with stable and dry weather throughout the year.
Although the weather is quite stable during the dry season in Panama, weather – like all over the globe – can never be precisely predicted or planned. For both seasons, we can make no guarantees and suggest being flexible.
